NASAEuropa (4/28/2009)

Jupiter's moon Europa has a crust made up of blocks, which are thought to have broken apart and 'rafted' into new positions, as shown in the image on the left. These features are the best geologic evidence to date that Europa may have had a subsurface ocean at some time in its past. Combined with the geologic data, the presence of a magnetic field leads scientists to believe an ocean is most likely present at Europa today. In this false color image, reddish-brown areas represent non-ice material resulting from geologic activity. White areas are rays of material ejected during the formation of the Pwyll impact crater. Icy plains are shown in blue tones to distinguish possibly coarse-grained ice (dark blue) from fine-grained ice (light blue). Long, dark lines are ridges and fractures in the crust, some of which are more than 1,850 miles long. These images were obtained by NASA's Galileo spacecraft during Sept. 7, 1996, Dec. 1996 and Feb. 1997 at a distance of 417,489 miles. Image Credit: NASA/JPL/University of Arizona
